"The purpose of the party was to disclose the gender of Cheyanne Willis' unborn child," the initial police report read. “[We] have been given information we have found to be false. Hours and days have been wasted following leads known to be lies when they were provided to our officers. From the very beginning of this investigation, we have met significant resistance that is uncommon from victims of crime wanting a resolution.”

Police said two gunmen walked into the front door of the home where the party was held the night of July 8 and fired at least 14 rounds, shooting nine people, including three children.

Police haven't identified the gunmen or their motive.

An unloaded handgun found at the scene is being examined by police, according to a report.

There is a $10,000 reward for information leading to an arrest in the case.
